## What project S40 buys

This funding line is directly aligned to the U.S. Army Air and Missile Defense (AMD) Modernization Priority. The Army Integrated Air and Missile Defense (AIAMD) program is a designated Major Defense Acquisition Program (MDAP), a critical component of the Army's AMD strategy, and is a top AMD Cross Functional Team modernization priority program. The funding in this PE provides for hardware upgrade of end items to include design engineering and development changes needed prior to implementation into the baseline. Funding in FY 2026 and FY 2027 also supports convergence of AMDPCS into the IBCS hardware baseline. In FY 2026, appropriate effort and funds were realigned to PE 0606118A, AIAMD Software Development & Integration to support entering into the Software Pathway. AIAMD is directly aligned to the U.S. Army Air and Missile Defense (AMD) Modernization Priority. The AIAMD program is a direct response to the U.S. Army AMD Concept and Operational and Organizational (O&O) Plan for the Future Force, the AIAMD System of Systems (SoS) Capabilities Development Document (CDD) and the AMD Task Force Concept of Operations (CONOPS) and a top Cross Functional Team Priority. The AIAMD Program is uniquely structured to enable the development of an overarching SoS/Integrated Fires capability with all participating Department of War (DoW) Air Defense Artillery (ADA) components functioning interdependently to provide total operational capabilities not achievable by the individual element systems. This funding will optimize effort to modernize air defense systems under an Integrated Fires architecture to manage and defend the battlespace in a joint environment against complex threats using the Integrated Battle Command System (IBCS) as the centerpiece. The AIAMD program achieves this objective by establishing the AIAMD SoS architecture and developing (1) the IAMD Battle Command Systems (IBCS) Engagement Operations Center (EOC) to provide the common Mission Command capability, (2) the Integrated Fire Control Relay capability for fire control connectivity and distributed operations, and (3) the common Plug and Fight (P&F) Kits to network-enable multiple sensor and weapon components including the IBCS EOC.

**R-3 lines of work:** Product Development; Test and Evaluation.

### IBCS/AMDPCS Hardware Convergence

Funding in FY 2027 will support development and systems engineering activities for the fabrication and integration of IBCS/ADAM prototypes at the A/B interface. Efforts include hardware and software design, updates to interface control documentation, interoperability and data exchange testing, and end-to-end system validation to ensure…

### Product Development - Beyond Initial Operational Capability (IOC)

**FY2025 accomplishments.** Funding in FY2025 provides support for software development and integration testing as well as the Guam Defense Systems (GDS) support for the planned architecture. Agile software development continues to support enduring development efforts and includes software fixes and improvements to counter emerging threats and incorporate emerging technology. Funding supports IBCS agile software development and integration, developmental and operational testing and requirements verification of the software build, operational testing, and integration activities for integrated fires capabilities. It also expands software factory development capacity to enable multiple 1-N capability items to be worked concurrently as defined by emerging joint Warfighter priorities. Funding provided for integration of additional Post-IOC 1-N capabilities such as: Sentinel A4, RIG-360, Army Long Range Persistent Surveillance (ALPS), F-35 Joint Striker and Terminal High Altitude Area Defense (THAAD). In addition, funding provides for the continuation of the Software Integration Facility (SWIF) a Government-Owned, Government-Operated software development, integration, and test capability. Also included is the software development for Forward Area Air Defense Command and Control (FAAD C2) Convergence into IBCS, as well as funding to support development of AMD Capabilities.

### Test and Evaluation - Beyond IOC Capability

**FY2025 accomplishments.** Continues Modeling and Simulation efforts at the Contractor Systems Integration Lab, Government Systems Integration Lab, Joint Interoperability Test Support, Army Test and Evaluation Center, Orange Flag, Project Convergence, Joint All-Domain Command and Control (JADC2), Integrated Fires Test Campaign (IFTC), and White Sands Missile Range test support for developmental test activities. Specific test efforts include: software development, component integration testing, software requirements verification, and system of systems capability validation consistent with the 1-N list. Funding includes test hardware requirements as well as lab infrastructure for additional test lines to integrate the 1-N list.
